The xpcc framework consists of powerful hardware abstraction layers for many
different microcontrollers, a set of drivers for various external targets and a general purpose toolbox for building hardware orientated applications.

The main goal of xpcc is to provide a usable API for barebone microcontroller programming,
which is efficient enough to be deployed on a small ATtiny, yet powerful enough to make
use of advanced capabilities found on the 32bit ARM Cortex-M.

xpcc is battle-tested in the real-world, highly competitive
environment of Eurobot.
It is the foundation of all of @RCA_eV's robot code, and is the
culmination of many years worth of effort, experience and improvements.

The source code is freely available under a 3-clause BSD license, so feel
free to fork this project and adapt it to your needs.
The only thing we ask of you is to contribute your changes back.
That way everyone can profit.

All of these targets are compiling and booting correctly
(★)
and have GPIO and UART working
(★★).
Most targets have support for basic peripherals, like I2C, SPI and ADC
(★★★)
as well as complicated peripherals, like Timers, CAN and external memory
(★★★★).
We also use a few targets in everyday development, which are very well tested
(★★★★★).

While the xpcc API is designed to be portable, we are only a small team of developers and are limited in the amount of platforms we can support and test in hardware.
The following microcontrollers should be able to compile, but have not been tested extensively in hardware:

All AT90 targets

All ATtiny targets

All ATmega targets

All STM32F0 targets

All STM32F1 targets

All STM32F3 targets

All STM32F4 targets

All STM32F7 targets

There are more platforms which we have prepared, but currently not finished support for (Xmega, STM32F2, STM32L).
Drop us an email to ask if your specific target is supported out-of-the-box and what you can do if it's not.

During the last decade the Roboterclub Aachen e.V. has developed a software library for communication among components that are distributed on PCs and microcontrollers. This library was used in autonomous robots for the Eurobot competition.

In 2009, xpcc became a separate project and since then focussed on a new approach to cross target microcontroller libraries. Over the years xpcc grew from a communication library to a general purpose framework suitable for all kinds of embedded applications.
